Expert Witness Services
Independent Expert Evidence for Complex Engineering Disputes
Engineering and construction disputes frequently turn on technical issues that lie beyond the expertise of courts, tribunals, and legal teams. When the integrity of a weld, the progression of a corrosion mechanism, or the adequacy of a fabrication inspection regime is at the centre of a dispute, the clarity and credibility of expert evidence can determine the outcome.
AHB provides independent expert witness services to legal professionals, insurers, loss adjusters and organisations involved in engineering and construction disputes. Our role is to analyse the technical evidence, assess the engineering issues in dispute, and present impartial expert opinion in a form that assists decision-makers in reaching informed conclusions.
We do not advocate for parties. We provide objective, evidence-led analysis grounded in decades of practical engineering experience in some of the most technically demanding industrial environments worldwide.
What We Do
AHB prepares and delivers expert evidence across the full range of proceedings in which engineering disputes arise:
- Expert Reports
Preparation of independent expert reports for litigation, arbitration, adjudication, mediation, insurance disputes, and regulatory investigations. Reports are structured to address the technical issues in dispute clearly, objectively, and in a form that assists courts, tribunals, insurers, and decision-makers.
- Joint Expert Statements
Participation in expert meetings and preparation of joint statements that accurately record areas of agreement and disagreement between technical experts, helping to narrow the issues in dispute.
- Oral Evidence & Hearings
Support through hearings, arbitrations, adjudications, mediations, and other proceedings where expert evidence is required, including the presentation of technical evidence and oral testimony.
- Independent & Single Joint Expert Appointments
Appointments as both party-appointed and single joint experts, providing independent, impartial, and evidence-based technical opinions to assist courts, tribunals, insurers, and decision-makers.

The strength of expert evidence depends on the credibility of the expert, the rigour of the analysis, and the clarity with which complex technical issues are communicated to a non-technical audience.
AHB brings all three. Our experts combine hands-on practical experience at the highest levels of industrial engineering with advanced academic qualifications, chartered professional status, and specialist expert witness training. We have been appointed in disputes involving nuclear infrastructure, major international power plants, petrochemical facilities, aviation fuel pipelines, steel bridge structures, and large-scale construction programmes across arbitration, litigation, adjudication, and insurance contexts.
We understand what legal professionals need from expert evidence, and we deliver it.
